Soil Science for Gardeners: Working with Nature to Build Soil Health

by Robert Pavlis

Overview

Build healthy soil and grow better plants

Robert Pavlis, a gardener for over four decades, debunks common soil myths, explores the rhizosphere, and provides a personalized soil fertility improvement program in this three-part popular science guidebook.

Healthy soil means thriving plants. Yet untangling the soil food web and optimizing your soil health is beyond most gardeners, many of whom lack an in-depth knowledge of the soil ecosystem.

Soil Science for Gardeners is an accessible, science-based guide to understanding soil fertility and, in particular, the rhizosphere – the thin layer of liquid and soil surrounding plant roots, so vital to plant health.

Coverage includes:

• Soil biology and chemistry and how plants and soil interact
• Common soil health problems, including analyzing soil's fertility and plant nutrients
• The creation of a personalized plan for improving your soil fertility, including setting priorities and goals in a cost-effective, realistic time frame.
• Creating the optimal conditions for nature to do the heavy lifting of building soil fertility

Written for the home gardener, market gardener, and micro-farmer, Soil Science for Gardeners is packed with information to help you grow thriving plants.

What People are Saying About This

From the Publisher

"Robert Pavlis once again proves science is wonderful! Soil Science for Gardeners explains why things work in your garden! Equally important, Pavlis uses science to destroy so many gardening myths. This is a book for all gardeners, especially the curious ones."
— Jeff Lowenfels, author, DIY Autoflowering Cannabis and the Teaming With Trilogy

"Robert Pavlis speaks the language of plants. More to the point, while he understands the science of healthy plant life he knows that none of this knowledge is very useful to the average gardener (nor of much interest) until it is distilled into language that we understand. Voila! Soil Science for Gardeners. This book will help readers understand the language of horticulture as it relates to soil. And good soil health is the foundation of every great garden and every successful garden experience. You will become a more confident gardener and your enjoyment of the gardening experience will be that much deeper. I will place my copy of this book within easy reach for future reference. Its pages will become well-worn from use long before it becomes compost. And in my books, composting a good book after it has served its purpose is a high compliment. From book to earth, from earth to life. From life to book. I predict that your reading experience of this book will enlighten and inform you like no other."
— Mark Cullen, C.M., president, Mark's Choice, co-author, Escape to Reality

"Like many gardeners, I use soil all the time, yet rarely give it much of a thought. But Soil Science for Gardeners takes you behind the scenes to the underground world of soil: what it is, its inhabitants, and how to use soil to really get the gardening results you want. Much of what you thought you knew about soil is simply not true and you'll learn why, plus how to make the soil you garden as healthy as possible. Painless science, practical knowledge. Read it from beginning to end!"
— Larry Hodgson, the Laidback Gardener

"Good gardens start from the ground up. In Soil Science for Gardeners, Robert Pavlis tells what's going on in soils and then offers practical directions to manage soil for more productive and healthier plants."
— Lee Reich, author, The Ever Curious Gardener

"Natural systems are more than the sum of their parts. And yet to understand them we must closely examine these parts. Soil Science for Gardeners takes us on a journey through the microscopic levels of soil geology, chemistry, and biology, and illuminates the soil ecology that sustains all life on land. From this knowledge base it then teaches us strategies and methods to regenerate and sustain life giving soil."
— Darrell E. Frey, author, Bioshelter Market Garden and co- author, The Food Forest Handbook

"Thank goodness for this book! If I had one wish for all gardeners, no matter their experience, I'd wish for them to endeavor to understand the vital role that soil plays in gardening success, and then, I'd have them read this book for the most comprehensive understanding behind it all. As a self-proclaimed soil super-fan, this is the most comprehensive book on the subject I've ever seen. I've been following Robert's work for a long time and I trust his science-based, no-nonsense approach to helping us all debunk gardening myths while making us all smarter gardeners in the process. Robert is one of my trusted, go-to sources when I want to get to the bottom line, and this book does that in spades. Soil Science for Gardeners will teach us everything we want and need to know about the critical role soil plays in the success of our garden and landscape, and more. It's extremely well thought out, comprehensive and a joy to read: practical wisdom for real life application in all our gardening pursuits. Three cheers for Soil Science for Gardeners!"
— Joe Lamp'l, Creator and Host of Emmy Award-winning PBS television series, Growing a Greener World® and Founder, joegardener.com and The joe gardener® Show podcast

Editorial Reviews

01/20/2020

Pavlis (Building Natural Ponds), owner of the botanical garden Aspen Grove Gardens, in Ontario, Canada, brings fresh life to a dry topic, digging deeply into the science of soil health in this understated and informative manual. Writing that “growing plants is very easy if you understand the soil below them,” Pavlis instructs on scientific basics (“there is more biodiversity in the top foot of soil than anywhere else on Earth”), weighs in on such garden practices as tilling and mulching, and gives advice on developing a personalized plan (“Don’t do things in the garden because someone told you it is a good idea; do them because you know how they impact plant growth”). Pavlis is skeptical about professional soil testing, while making suggestions for several different DIY tests (including burying a pair of white cotton underpants; if the soil is microbe-rich, the microbes will eat the cotton). Sidebars do quite a bit of myth busting, such as of the oft-touted ratio of “browns to greens” in compost, or that “soil is a living organism” that requires “feeding.” Full of valuable information for both home and professional gardeners, Pavlis’s step-by-step primer breaks down a complex topic in a manner both entertaining and easily understood.
